I'll continue to ride on the road, because I enjoy it, and it's convenient. I will say that I enjoy it more since recently getting a Garmin Varia radar tail light, it's nice to know when the cars are coming/passing, and the variable flashing helps make me more visible.
That being said, I do love getting out on the gravel and away from the cars. I'm very much looking forward to riding a gravel century next week without seeing a single car (except for a few road crossings, but there are no vehicles on the gravel, just other bikers, pedestrans, and horses).
